LG-8917

🛠 Summary of changes

This is part of the epic for the work around creating a script for PSE's to generate YAML that is easier, cleaner and more consistent.

These are some very minor changes to the seeders so that we can run the compare_yaml.rb script created in the PR here

Also a gitignore update because the serialized directory needs to be copied over from the config in order to run the script and I don't want it to get accidentally commited.

📜 Testing Plan

If you want to test the code for grouping the iaa_order diffs, you can add a binding.pry under line 30 checking for value.length > 1 and update some attributes in value to see that the diff is returned without multiple entries for the same account.

Lint is mad, but the code itself looks good. Looks like lint isn't happy with your indentation, which I think was set to 4 spaces instead of 2.

@mitchellhenke I rebased and that fixed the security issue but now I'm getting an error in one of the specs.. I'm not sure how the minor changes made here would effect that test

That seems like a flaky test from #8345 (cc @zachmargolis)
